摘要： A continuous casting apparatus includes a dispensing assembly for introducing granular mold flux onto the top of a slab being cast within a continuous casting mold. The apparatus has a delivery apparatus for feeding granular mold flux from an intermediate hopper to the top of a slab being cast, and the delivery apparatus has at least one delivery tube assembly interconnected with the intermediate hopper, with a mechanism for controlling the flow rate of the mold flux through the delivery tube assembly. In the first two embodiments, the flow rate control mechanism is a variable diameter pinch valve located between the intermediate hopper and the delivery tube assembly. In the third and fourth embodiments, the flow rate control mechanism is an air pump and a mechanism for varying the air volume through the air pump so that the granular mold flux delivered is a function of the air volume of the air pump.

摘要： Surface defects in rolled steel are remedied by quenching a surface layer of the strand immediately downstream of the caster by transversely differential quenching to match the transverse temperature profile of the strand. The flow rate of the quench spray is differentially adjustable across the width and optionally the length of the strand. An array of spray nozzles controlled by groups provides the quench spray.

摘要： Sound detection techniques and sound discrimination techniques are used to analyze the real time sounds generated during the operation of cleaning heads operating within a vessel to determine if the cleaning heads are operating properly. During a typical cleaning operation pressurized cleaning solution is dispensed through a rotating nozzle assembly inside the vessel. As the nozzles rotate the spray moves about the interior of the vessel creating a unique sound pattern. By placing one or more pickups on the exterior of the vessel the sound is captured and fed to an analyzing device for analysis. Key properties such as, but not limited to, sound pressure levels, amplitude variations, spectral content, and rotational information are extracted and analyzed against the reference parameters.

摘要： In a method for casting prefabricated products in a continuous casting device, having a casting mold and a strand guide downstream of the casting mold, wherein the strand guide has rolls positioned opposite one another in pairs for supporting and guiding the solidifying cast strand, wherein some rolls are drive rolls and others are idle rolls, wherein drives are provided for the drive rolls, and wherein the drive rolls are adjustable against the cast strand in order to transmit guiding forces and strand conveying forces onto the cast strand in interaction with the idle rolls, the drive rolls and the drives are controlled to a preset rotational speed such that the drive rolls have circumferential speeds identical to one another within the limits of a preset casting speed. The motor torques of the drives are maintained at a level as equal as possible below a permissible torque limit value relative to a loadability of the strand shell.

摘要： An apparatus and method for measuring the level of a free surface of molten metal in an electromagnetic continuous casting process using an AC electromagnetic field. A detection coil is provided to detect the sum of a magnetic field applied from an induction coil and an induced magnetic field based on eddy current in the molten metal. An arithmetic unit is provided to detect the surface level of the molten metal by removing a variation of the applied magnetic field with a variation in current to the induction coil from an output signal from the detection coil. The surface level of the molten metal can be accurately measured by determining whether a variation in the output of the detection coil results from a variation in the applied magnetic field or a variation in the surface level of the molten metal.

摘要： A method of fabricating a porous metal structure of a molten liquid metal within a casting chamber to form a porous solid structure upon controlled chamber cooling and depressurization. The method includes provision of a pressurizable stationary mold casting chamber having a gas pressure release valve, a gas pressure measurement sensor, and a plurality of sites with respective surface-temperature or heat flux sensors and respective independently operable temperature controllers for regulating each respective site temperature. A data base driven microprocessor receives pressure and temperature data and selectively and independently adjusts pressure and temperature in accord with algorithmic commands relative required pressure reduction for pore formation and cooling for solidification to chosen extents of porosity and of solidification over a time period terminating upon porous solid-structure fabrication.

摘要： The invention relates to a method for controlling the temperature of a melt (10), preferably of a steel melt, in a distributing vessel (11), whereby the temperature of the melt is measured, the measured result is compared with a predetermined temperature range in the form of specified values, and as much heat is supplied or withdrawn from the melt such that the temperature remains inside said range. In order to control the melt temperature, a fireproof shaped part (20) which is closed on both sides and which is provided for accommodating a liquid cooled induction coil (1) is immersed in the melt (10). The transmission of heat is carried out by means of thermal conduction out of the wall of the shaped part (20) which is coupled to the induced electromagnetic field and/or by means of a direct coupling to the liquid melt (10). The shaped part (20) accommodates the induction coil (1) in an interhangeable manner while leaving cooling channels (9) open and is positioned from the outside by a manipulator (16) which can be lifted, lowered and tuned.
